Invoke-UDJavascript Returns null Unexpectedly

[parzog]

Description of Issue

Reference forum post #11799 - When attempting to run Invoke-UDJavascript without user interaction to return a value (such as using window.localStorage.theme to retrieve the current user's dark/light mode selection) returns null instead of the value expected. The output is correct when ran with user interaction, such as the following:

New-UDApp -Content {
    New-UDButton -Text "h" -OnClick {
        Show-UDToast -Duration 10000 (Invoke-UDJavascript -Javascript "window.localStorage.theme")
    }
}

I'm not seeing this behavior in 5.5.0. This is my example app. I also added a call in a New-UDDynamic to see if it differed but it is the same. I see 2 toast messages. Do note, that this value isn't set unless the user has clicked the button. If it hasn't been clicked the value will be $null

New-UDApp -Content { 
    Show-UDToast -Duration 10000 (Invoke-UDJavascript -Javascript "window.localStorage.theme")
    New-UDDynamic -Content {
        Show-UDToast -Duration 10000 (Invoke-UDJavascript -Javascript "window.localStorage.theme")
    }
}
